ValueError in Donut

[Maxi Fischer]

This is the output of running Donut on the new multivariate outliers (PR #72 ):

2018-06-13 01:05:21 [ERROR] src.evaluation.evaluator: An exception occured while training Donut on Synthetic Multivariate Outliers: The shape of ``arrays[1]`` does not agree with the shape of `timestamp` ((1000, 1) vs (1000,))

Somewhere we should us "reshape(1, -1)" to add a dimension. Or drop one using slicing operator.
